Bruno Mars is donating $1 million from his Michigan concert to aid those affected by the Flint water crisis. Mars told the audience Saturday at his show in Auburn Hills that he and tour promoter Live Nation are redirecting funds from the concert to The Community Foundation of Greater Flint, a charity.

In 2014, Flint switched water sources and failed to add corrosion-reducing phosphates, allowing lead from old pipes to leach into the water. Mars says in a statement that “as people, especially as Americans, we need to stand together to make sure something like this never happens in any community ever again.”
